simplify: sqrt (7) / (9)
a) sqrt 7
b) sqrt (63) / 3
c) sqrt (63) / 3
d) sqrt (7) / (3)
Your notation is questionable.
1) I assume you meant sqrt (7/9)
If so, then the answer is 1/3 * sqrt7 which is answer d.
thanks
To simplify the expression sqrt(7) / 9, we can start by simplifying the square root of 7. The square root of a number can be expressed as a rational number if the number inside the square root is a perfect square. However, 7 is not a perfect square, so we cannot simplify it further.
Therefore, the simplified form of sqrt(7) / 9 is sqrt(7) / 9.
So, the correct answer is choice d) sqrt(7) / 3.
